An interesting look at the history of candy and Halloween - a very recent invention.
Would you believe the earliest trick-or-treaters didn’t even expect to get candy? Back in the 1930s, when kids first started chanting “trick or treat” at the doorbell, the treat could be just about anything: nuts, coins, a small toy, a cookie or popcorn ball. Sometimes candy too, maybe a few jelly beans or a licorice stick. But it wasn’t until well into the 1950s that Americans started buying treats instead of making them, and the easiest treat to buy was candy. The candy industry also advertised heavily, and by the 1960s was offering innovative packaging and sizes like mini-bars to make it even easier to give out candy at Halloween. But if you look at candy trade discussions about holiday marketing in the 1920s and 1930s, Halloween doesn’t even get a mention.
